Allouch, Nizar; Meca, Ana; Polotskaya, K. - 2021

In this paper, we develop a new game theoretic network centrality measure based on the Shapley value. To do so, we consider a coalitional game, where the worth of each coalition is the total play in the game introduced in Ballester et al. (2006). We first establish that the game is convex. As a...

Chain stability in trading networks

Hatfield, John William; Kominers, Scott Duke; Nichifor, … - In: Theoretical economics : TE ; an open access journal in … 16 (2021) 1, pp. 197-234

In a general model of trading networks with bilateral contracts, we propose a suitably adapted chain stability concept … that plays the same role as pairwise stability in two-sided settings. We show that chain stability is equivalent to … stability if all agents' preferences are jointly fully substitutable and satisfy the Laws of Aggregate Supply and Demand. In the …

Contagion in stable networks

Bougheas, Spiros P. - 2017

We study the formation of networks in environments where agents derive benefits from other agents directly linked to them but suffer losses through contagion when any agent on a path connected to them is hit by a shock. We first consider networks with undirected links (e.g. epidemics,...

Aggregation in networks

Allouch, Nizar - 2021

In this paper, we show that a concept of aggregation can hold in large network games with linear best replies. Breaking up large networks into smaller subnetworks, which can be replaced by representative players, leads to a coarse-grained description of strategic interactions. This method of...

Chapter 14. Diffusion, Strategic Interaction, and Social Structure

Jackson, Matthew O.; Yariv, Leeat - In: Handbook of social economics : volume 1, (pp. 645-678). 2011

We provide an overview and synthesis of the literature on how social networks influence behaviors, with a focus on diffusion. We discuss some highlights from the empirical literature on the impact of networks on behaviors and diffusion. We also discuss some of the more prominent models of...

Chapter 12. An Overview of Social Networks and Economic Applications

Jackson, Matthew O. - In: Handbook of social economics : volume 1, (pp. 511-585). 2011

In this chapter, I provide an overview of research on social networks and their role in shaping behavior and economic outcomes. I include discussion of empirical and theoretical analyses of the role of social networks in markets and exchange, learning and diffusion, and network games. I also...

Overlapping coalitions, bargaining and networks

Agbaglah, Messan; Ehlers, Lars - 2010

This paper extends the theory of endogenous coalition formation, with complete information and transferable utility, to the overlapping case. We propose a cover function bargaining game which allows the formation of overlapping coalitions at equilibrium. We show the existence of subgame perfect...
